BOTTLE-WASHING MACHINE.

Application med January 26.1927. .serial No. 163,669.

This invention relates to improvements in receptacle washing a paratus, and more partlcul'arly to m`eans or anchorin receptacles to the carriers of such washlngmachines.

The primary object in view is the easily releasable, effective, and simple anchorage of a bottle or like receptacle within its pocket or chalice, aiiixed to the carrier of the washing apparatus for4 insuring retention of the vreceptacle in the proper alignnient and condition for being effectively subjected to cleansing actions.

With this. and further objects in view, as Will in part hereinafter become apparent and in part be stated, the invention comprises retaining devices so coordinated with the pockets or other holders ofv receptacle washing machines as to enable locking of the receptacles therein by the act of assembling them in the machine, and unlocking the receptacles by the act of ,removing them from .the machine, while insuring effective retention during the progress through the machine.. p

The invention is especially well adapted for use in conjunction with the type of washing apparatus disclosed inthe joint p application of yHarry D. Lathrop and me, iiled July 31, 1925, Serial 47,194.

The invention comprises certain other novel constructions, combinations, and arrangements of parts, as will be hereinafter specified and subsequently pointed out in the appended claims. A

In the accompanying drawing:

In bottle washing machines of the general type to which the present invention 1s particularly applicable, it has'been heretofore ro osed to retain the bottles being washed 1n t eirl proper relat'on to the carrier of the lmachine by various forms of more or less l,crude and expensive apparatus. A well known expediency to this end is mcluded 1n wide range of the employment of a rod or rods extending. l

along and substantially midwa above the path ofthe receptacles, and :su cientlyiadjacentthe 4plane of ltravel .of the upperkex-` tremitiesof the receptacles to preclude, longitudinal displacements of the receptacles from. their pockets. .Diiiicultyhasbeen experlenced with such'l arrangements, however, to successfully confine the receptacles without excessive friction, and even in the most successful embodiments employing restrainlng rods, objectionable lateral play of the receptacles frequently occursy and results in lack of effect-ive alignment of the receptacles with respect to the path of the cleansing jets. Where substantially 'high pressure- 1s employed `for the liuid of the jets, ysay 35 pounds, which has been found a very satisfactory pressure, receptacles in such known apparatus have been lifted by the pressure of the jets out of their pockets after playlng laterally toone side orthe other of the restraining rod or-rods. l

It is a primary object of the resent invention to overcome all these di culties and to gam other substantial and valuable advantages as will subsequently become aparent. I Referring to. the drawing by numerals, 1 indicates the usual endless belt or carrier for the receptacles to be washed. As shown, the belt l comprises a chain,.but may consist of any suitablesu-bstitute. Anti-friction rollers'2 sustain the belt 1on the horizontal flange of a angle bar track 3. Paralleling `the tra-ck 8 throughout the parts of the washing machine in which the cleansing op erations occur, as the above identified co-pending application, is a track ,4 of similar angle material, ar. ranged to face the track' and located relative thereto in a manner to receive and sustain the anti-friction rollers 5supporting the pockets or receptacle containers 6, each of which pockets is pivotally connected to thebelt 1. Each pocket 6 is a'duplicate of all others, and lis susceptible, of course, of a modification in detailed con-v to the v'particular recepstruction according taclevto be treate Each pocket 6, howconslsts of an openwork framing inclu ng longitudinally disposed bars 6'., and circumferential, integral rings connectin said bars; Bottom plates 6 form a parto pocket 6, and are disposed to ever, preferabl inthe machine shown in lll directly 4support the presented terminus of from the carrier or belt 1, producing the.

flanges. 9. spaced apart and adapted to receive therebetween a web l0.y which projects laterally from the respective pocket- 6. Webs 10 may comprise various forms, but preferably each consistsl of a pair of' parallel plates, spaced apart aty l2. as seen in Fig. 3, sufficiently to cause the webs to be effectively guided by flanges 9 while free to' swing therebetween. Webs 10 are pivoted at their lower portion to the lowerv portion of the fianges 9 in any desirable and effective manner, as by employment of a through bolt 11. Bolt 11 is preferably surrounded by a bush ing 13, but of course the pivot-al anchorage may beconstructed otherwise. as may be desired. The plate 7 terminates somewhat short of the length of the flanges 9 at the' lower end, and thus leaves an open notch 7',

so located as to accommodate the swing of pocket 6 to the lower position, after the manner indicated in .full lines in Fig. 1.v

By preference, the edge of each web 10 exposed toward the inner face of plate 7 is dimensioned and shaped to tit'against said plate when the pocket 6 is held in the upright position by the roller 5 traveling on a horizontal portion of track 4.

Each of the flanges 9 is formed `with an ledgewise extension 17 terminating in a nose 18, projecting through the open side of pocket 6 into position for snugly engaging thelp'articular receptacle 19 located in the pocket 6 when said pocket is in an upright position, as seen in Fig. 2. The nose 18 in each instance will, of course, be provided with lthat contour most effective in cooperating with the particular receptacles to be washed. For instance, when milk bottles are being washed, the nose 18 will *be rounded and proportioned to engage the side of the neck of the bottle and to overlie and engage the bead .16'present at the terminus of such neck. The bottles are mounted in an inverted. position. The bar 6" of pocket 6 diametrically opposite extension 17 is slightly difi'erent from all of the other barsY of the pocket it being'flat or slightly concave to facilitate loading or unloading of the bottles, while' the upper portions of all the other bars, as best seen in Fig. 2, are thickcned longitudinally to extend inside ofthe inner circumference of the upper ring ofment, of the pocket 6, so as to snugly engage the walls of the bottle 19-when in place in the pocket. The said Hat. bar 6 opposite nose 18 is preferably provided with an inwardly extending lug 15` adapted to cooperate with nose 18, especially relative to bottles or other receptacles o slightly reduced proportions but otherwise similar to those of the 'average conventional bottle. The difference in shape of the bar 6 having a lug 15 from the other bars causes a certain amount of clearance to appear at the right hand side of pocket 6 in Fig. 2 between the pocket and the bottle, whereas in fact, the bottle is in snug Contact with all of the other bars 6".

So far as the present invention is concerned, it is wholly -rmmaterial lwhat means may be employed for causing relative movement of the .pocket 6 with respect to the carrier belt, 1t being only necessary that the pocket. be permittedv to swing to an appropriate, inclined position, such, for example, as either of the inclined positions shown infull lines in Fig. 1, or any other location whereat the nose 18 is no longer in the path of the bead of receptacle 19, to enable said receptacle to be placed -in or removed from the pocket; In practicing the invention as applied to the washing machine disclosed in the above identified co-pending application, the track 4 is formed with movable sections 4', 4, pivotally sustained and adapted tobe actuated by links and power levers 14,14. Said links and levers 14 function to lowel' sections 4 and 4 to positions 100 with the pockets 6 swung downward on their pivots 11 to places where the nose 18 in each instance is no longer in the path. of movebead of bottle 19. lVhen in either of these positions, the bottle is free 105 to be inserted or removed to or from pocket v 46.. l/Vhen inserted, as seen at the right hand side of Fig. 1, and the track section 4'raised to alignment with the main portion of track 4, such movement 'causes the pocket 6 to 110 move across the extensions 17 so that the noses 18 thereof assumethe relation to the bottle 19 seen in Fig. 2, and the bottle is thereby effectively and substantially rigidly anchored in play` and `against possible vertical dsplacement. y

It will be apparent that iu operation the bottle. 19 will be firmly held in place throughout the traveling ot the carrier. 1 120 until the pocket 6 is again free to swing laterally relative to the carrier. lVhen this occurs, as seen at the left hand side of Fig. 1, the pocket 6 moves away from the detent' comprised of the noses 18 and thereby re-- 125 leases theV bottle 19 for easy withdrawal. Thus it will be observed that the locking apparatus is effective while locking of the receptacle is required, and, at the same time,

it does not interfere with the charging and ocket 6 both against lateral 115 I discharging of receptacles 1in the regular operation of the machine. Furthermore, no

especial provision must be made-for manipulation of moving parts in vorder t effect either the locking or the releasing of the receptacles relative to the pocket 6.
